Postfix as honeypot and other anti-spam related Qs

[Stef <stefmit () comcast net>]

I have been trying to design an anti-spam honeypot, utilizing (because 
this is what I have at my disposal) a postfix server. I have gone 
through the following material:

http://www.trackinghackers.com/solutions/sendmail.html
http://www.securityfocus.com/infocus/1747
http://www.securityfocus.com/infocus/1748

and I liked the first one. Here are the issues I am dealing with, right 
now:
- cannot find the equivalent of some the options mentioned in the 
sendmail-based article, related to postfix;
- wondering if there could be more about such a setup, as far as 
logging/processing of logs/reporting (perhaps automatic - I am thinking 
here of some automatic way of informing the spamcop.net of the 
world?!?)

Any ideas/suggestions/links to help me understanding what more could I 
get out of the above, and postfix capabilities, would be highly 
appreciated.

One more note/question: the plan is to take a static public IP of a 
system I have available, and use it as MX record for a new domain I 
will be registering, via dyndns (so that my honeypot could be found as 
such by MX record scanning of domains, not only by TCP 25 scanning). I 
wonder what would be the chance that spammers would have tools to 
reverse lookup the IP address, and find out that the IP belongs in fact 
to another domain (i.e. I cannot - obviously - change the PTR record 
for an IP address!). And if found as such - what would be the chance to 
stop pursuing the "sweets"? Any ideas?!?

TIA,
Stef
